python-2.7 - virtualenv python-ldap安装错误

Question

请不要将此称为重复项。

到目前为止，所有的答案都只是通过全局安装 ldap 和其他开发包来“解决”问题，这并不能解决无法在虚拟环境中安装 python-ldap 包的问题。

示例包括:
How do I install python-ldap in a virtualenv on Ubuntu?

sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev

我在我的虚拟环境中使用 ubuntu 14.04、python 2.7 和 flask 。

当我运行 pip install python-ldap ，我收到以下错误。

如果我尝试 pip 安装任何建议的开发库，以便它们在我的虚拟环境中，我会收到以下错误。

  Could not find a version that satisfies the requirement libsasl2-dev (from versions: ) No matching distribution found for libsasl2-dev

我可以在全局范围内安装所有这些东西，但这完全违背了使用 virtualenv 的目的。

我真的很想找到一个有意义的 virtualenv 解决方案，因为我所能找到的只是针对 virtualenv 问题的非 virtualenv 解决方案。

谢谢。

Python 包 python-ldap 需要其他一些不是 python 库的库(libsasl2-dev，...)(因此您不能使用 pip 安装它们)。因此，要使用它们，您必须安装它们。两种解决方案:

使用你的包管理器来安装它们(例如:apt-get)；

下载它们的源代码并在本地编译它们(在您的 virtualenv 中)(在特殊情况下对某些库很有用)。

也许您可以尝试第二种解决方案？
